David Sterba e841c811d6 btrfs-progs: docs: generate section 5 to final name directly
There was a workaround for asciidoc/xmlto build because page btrfs.5 and
btrfs.8 used the same intermediate file. To avoid clash for the section
5 page it is part of the name, this is still needed, but for sphinx we
can use the final name as it will get the right suffix. This affects
only the generated manual pages.
